It is one of the measures of dispersion, that is a measure of by how much the values in the data set are likely to differ from the mean. The (N-n)/(N-1) term in the finite population equation is referred to as the finite population correction factor, and is necessary because it cannot be assumed that all individuals in a sample are independent.
